Antioch Request an Appointment“Exceptional cancer care requires that a physician understand not only a patient’s complex medical issues but appreciate the impact an illness has on his or her life and loved ones. As a physician I must be a guide for patients through harrowing times and promote the understanding of not only the best medical recommendations but how those recommendations affect the individual.”
